Ya ,its been over 3 months ,last seen over here.

Don't be angry :).Got some real company works and projects.

Anyways ,I am here with an amazing software tweak for your Samsung S3 galaxy phone ,that boosts your phone at least to 40-50% fast from the previous state.

I don't wanna blabber more :).Lets start.

Introduction - Samsung Galaxy S3

The Samsung Galaxy S III is a multi-touch, slate-format smartphone designed, developed, and marketed by Samsung Electronics that runs the Android operating system. It has additional software features, expanded hardware, and a redesigned physique from its predecessor, the Samsung Galaxy S II. The S III employs an intelligent personal assistant (S Voice), eye-tracking ability, and increased storage. Although a wireless charging option was announced, it never came to fruition. Depending on country, the 4.8-inch (120 mm) smartphone comes with different processors and RAM capacity, and 4G LTE support.The device was launched with Android 4.0.4 "Ice Cream Sandwich", was updated to Android 4.3 "Jelly Bean", and can be updated to Android 4.4 "KitKat" on variants with 2 GB of RAM. The phone's successor, the Samsung Galaxy S4, was announced on 14 March 2013 and was released the following month.

As you got some info about the phone S3 ,i am not gonna directly step into the tutorial.Before that ,you need to check the below requirements.


Woah!!! That was a heck of a list.

Before continuing i strongly recommend you to flash the Cyanogen mod from the requirements section.As I am gonna continue this tutorial with my Samsung Galaxy I9300 with Cyanogen mod 11.0(Android 4.4 Kitkat).

Let's dive in.


Note :- Considering you have a rooted phone with CWM(Custom recovery installed) and downloaded all the prerequisites.

  • Copy the and to your phone memory(/sdcard/).
  • Enter recovery mode by pressing Vol Up + Power key,when the device is off.
  • After getting into CWM,just navigate to Wipe or Format data and cache using Vol up and Vol down and use Power button to select the option.
  • First of all flash the downloaded Cyanogen mod zip file from the recovery(Press Vol Up + Power key,when the device is off ,to enter the recovery mode).
  • After a successful total wipe now select Apply update from zip file and select from your /sdcard/ and wait for the update to get finished.
  • Now reboot your phone ,now you can see the new Android 4.4.4 CM 11.0.Now switch your phone off and enter into the recovery mode once again and follow the previous steps to flash the boeffla kernel
  • Hurray!!! After a successful restart ,you can see your phone running on Android 4.4.4 CM 11.0 with boeffla kernel.

Tweaks to boost your phone to 40-50% faster.

  • After installing the Boeffla Config V2.apk ,click open the application from the app drawer.
  • Give root permissions to the application if you are notified to give.
  • The below picture shows ma phone's overview through the config application.
  • Now select CPU section and adjust the frequencies and tweaks as shown in the below picture.As you can see ,it will boost your phone to its max by squeezing your processor speed from 1.4 Ghz to 1.7 Ghz.
  • Now here comes the real tweak for gamers.Select the GPU section.And set the values as shown in the below picture.You may get bugged or get random reboots,if then just reduce the values correspondingly until your phone seems stable.But for me the below values are good and ma graphics processing works at its max..

  • Its better for you to give an overvolt +50 mV to your GPU for stability like below picture.

  • Now go to the Governor/IO section and select a governor shown as in the below picture.I prefer you to try every governors and select the best one for you.For me ,my phone seems good with "pegausq" governor.

Some other miscellaneous tweaks

  • As you know ,generally samsung's every mobile phones or tablets out in the market got low sound volume but got better quality audio.By tweaking the sound part of the kernel ,you can achieve above 80% of the current stock volume.You may adjust the sound on your own ,my preference is shown in below picture.

  • Configure some other miscellaneous tweaks like in the pictures below.

Hope you guys enjoyed the tutorial ,please feel free to subscribe and share.Don't be shy to ask your question through comment section.Blogger or facebook ,you decide :).

I will release the benchmark testing results of my phone within 2-3 hours.So stay tuned.
